If I was your bf, I would go over there and knock him out. And take Pooka back for you. (You'll love me forever wont you?)
Go for it, get her back. If she means that much to you in your heart, make that heart grow bigger and win Pooka's heart back to yours. Go now, while its still good. Why not have an officer get Pooka for you? Report your best friend. Thats illegal to steal a pet. Expectually that vulerable.
